C-XSC++ is a C++ class library for eXtended Scientific Computing. It is a complete overhaul of C-XSC, following the new
ISO-C++ standard. New C++ structures have been used as far as supported by recent compilers.

It provides real, complex, interval,
complex-interval, and multi-precision data types. There are also vector and matrix classes corresponding to
these scalar types. The interval data types are very useful for verified numerical computations.
